So ein Bullshit...For example, an ad group containing any of the following display URLs would comply with this policy because all URLs contain the same top-level domain, “example.com”:
* www.example.com
* www.widgets.example.com
* www.example.com/widgets/redwidgets/
* www.example.com/index.html
The following display URLs in the same ad group, however, would not comply with our policy because their top-level domains don’t match:
* www.example.com
* www.example.widgets.com
